831f551eec Now that we can call vmpagesize without having a vm to hand, the implementation of vmcreate can be simpler: in particular, the grain size can already be correctly rounded up.

88c85abc0e Vmpagesize now takes no arguments -- this avoids suggesting (incorrectly) that it might return a different value for each vm. 
New function ProtGranularity returns the protection granularity of the operating system. (On all currently supported operating systems this is the same as the granularity of memory mapping returned by VMPageSuze, but it's important to separate these concepts.) MPMCheck asserts that the granularity of memory mapping is a multiple of the granularity of protection.
Client arena supports MPS_KEY_ARENA_GRAIN_SIZE.
Some of the test cases set the arena grain size.

3c48eff730 On platform lii6gc, the mps needs a bunch of symbols which are not defined if the -ansi option is given to gcc. these can be enabled by defining features like _gnu_source, but all headers share a common set of features (via <feature.h>) and so all sources in the same compilation unit must turn on the same set of features. make sure this happens by turning on the features in config.h (not mpstd.h). 
Remove <string.h> from mpsi.h (not needed).

4009b8a559 Abolishing eventgen.pl. event structures are now expanded by the preprocessor. 
Abolishing event formats.  Each event now has its own structure.
Event parameters are now written directly into the event buffer, rather than being copied twice.

e82d034c98 Mps br/vmem: prepare for simple-chunk-return: 
arenavm.c: VMFree is okay for testing chunk-ret; though just sparePagesPurge() for now;
  diag.c: show what we want for using zcoll to show chunk-ret:
    VM_ix_Create/Destroy
    TraceStart, excpet only briefly for dyn-crit (why=2) and not at all for minor
  locus.c: no newline on "condemn gens" diag please
  tract.c: ChunkDecache is BROKEN; just add AVER to catch this for now
  vmix.c: VM_ix_Create_ok/VM_ix_Destroy (vmw3.c needs similar)
  zcoll.c:
    release after mps_arena_collect!!!
    make, collect, make, collect, to show chunk-ret
    10MB arena means many chunks
None of this is releaseable quality of course.
